GROUND-LEVELING MACHINE.

Specification of Letters Patent. Patented Ma 31 1921;

7 Application filed August 13, 1920. Serial No. 403,389.

To aZZw/wm it may concern Be it known that I, MICHAEL JANKIEVIOH, acitizenof Lithuania, residing at Elmhurst, county of Queens, and Stateof New York, have invented certain. new and useful Improvements inGround-Leveling Machines, of which the following is a specification.

This invention relates to improvements in ground leveling machines,particularly to machines for preparing and leveling the ground of tennis"courts, play grounds, baseball parks, drive-Ways, and the like.

It is the principal object of the invention to provide a machine whichlevels the ground by collecting stones and other oby, structions,provides layer of sand, clay or i which one or the other of the levelingmeans may be conveniently cut out of operation while for instance theprepared groundis firmly rolled out by rollers, and which can be easilysteered during all these operations by the operator.

With the above and other objects in view,

a this invention resides in the'novel features of construction,arrangement of parts and combination of elements to be hereinafter morefully described,'claimed and illustrated in the accompanying drawings inwhich Figure 1. is a top plan view of the machine constructed accordingto the present invention. i

In the machine frame 10 a motor 11 is mounted provided with a startinghandle 12 and clutch throwing lever 13. Near its lower rear end theframe carries a platform 14: for the operator and in front of the samesteering wheel 15 for the operation of the steering roller 16 on theaxle 17 suspended by hangers 18, 19 and 20 .of which 19 is suspendedfrom a bar 21 Fig. 3 secured in the side walls 21 and 22 of the framethrough the center of which a steering shaft 23 is extending, the lowerend of which is secured to the roller 16 and which passes through aturn-table 24 coiiperating with a similar turn-table 25 suspendedfromthe platform 26, carrying the motor,by means of rods 27 and 28.

In front of the motor the platform 26 carries a pair of links 29 inwhich a shaft 30 is journaled carrying a sprocket wheel 31 3 on one, anda similar wheel 32 Fig. 1 at the opposite side of the machine. Inapproximately its'middlethe shaft 30 carries a fixed clutch member 33and a movable clutch member 34 coeperating with the member 33 Fig. 1over which a belt 35 is running, guided over the motor shaft andadapted. to be operated by the belt shifting lever 13.

Over the sprocket wheel 31 a chain 36is guided which is also guided overa sprocket wheel 37 upon the axle 38 of a roller 39 j ournaled in themachine frame. On the axle 38 is also mounted in front of the sprocketwheel 37 another sprocket wheel 10 over which a chain 41 is guided whichruns over a sprocket wheel 42 on a shaft 43 journaled in the machineframe 10 which shaft carries within a hopper 414 at the front end of themachine frame a stirring device 45 for the sand or clay-4:6 with whichthe hopper is filled for a purpose hereafter more fully to be described.a

The hopper 4.4 has in its rear wall a door or opening 4L7 adapted to beclosed by the slide 48 sliding in guides 19 and 50 secured to the outerwall of the hopper. This slide has at its outer face the shape of a rack51 with the teeth 52 of which the teeth 53 of a periphery of the roller16, while a similar holder 62 is secured to the machine frame andcarries a brush 63 working against the periphery of the roller 39 tokeep the same clean.

On a shaft 64, journaled in the machine frame, a sprocket wheel 65 issecured over which a chain 66 is guided, running over a sprocket wheel67 on a crank shaft 68 journaled in the frame near the bottom thereof.The shaft 64 is rotated by means of a belt 69 guided over a pulley 70 onsaid shaft laterally disposed to the sprocket wheel 65 which is alsoguided over a pulley 71 by the side of the sprocket wheel 31 on theshaft 30.

The crank shaft 68 is connected by links 7-2 and 7 3 with a movableplate 7 4 carrying rake teeth 75, or if desired, with a plate 7 6carrying a brush 77 as indicated in Fig. 5. These plates areexchangeably held within a frame 78 secured in the sides of the machineframe and provided with upstanding links 7 9 to the upper ends of whichthe front end of an operating lever or rod 80 one on each side of themachine is pivotally secured at 80 which is extended to the rear of themachine and through the rear wall thereof where it is provided with atoothed segment 81. Intermediate its length the rod 80 is provided withnoses upon which are pivoted pivotal link connections 82 and 83 as shownin.Fig. 2. V

The front wall'of the hopper is extended as at 84 in order to guide thesame in front of the roller 39, while in front of this extension 84 aholder 85 is secured to link connection 82 and this holder carries astone rake 86 suspended on the opposite side of the machine frame in asimilar manner as indicated at 87 Fig. 7 In front of said rake 86a shaft88 is journaled in the machine frame and carries a sprocket wheel 89over which a chain 90 is guided which also runs over a sprocket wheel onthe shaft 64. On the shaft 88 a pulley 91 is secured laterally disposedto the sprocket wheel 89 over which a conveyer 92 is running which isalso guided over a pulley 93 of a stone collector 94 secured at thefront end of the machine frame which is provided with a front door 95 atits lower front end through which the stone may be removed. To the link83 is pivotally secured a holder 83' which is rotatably secured to oneend of a shaft 95, our naled with its other end in the opposite sidewall of the machine, which. shaft or axle 95 carries a wire brush 96. Achain 81 is connecting the wheels 81 at the rear wall of the machine.

Near the sprocket wheel 31 on one end of the shaft 30 is secured a fixedclutch member 101 adapted to be engaged by a movable clutch member 102on shaft 30 which is adapted to be operated by means of an op eratinghandle 103 at the rear of the machine platform 26. By means of thisclutch the rake operating shafts and gears are connected to the drivingshaft and when it is desired to dispense with their services during theoperating of the other elements, for instance the brush elements, theclutch member 101, 102 are separated by the suitable operation of thehandle 103.

In a similar manner the sprocket wheel 32 on shaft 30 near the oppositeend thereof has laterally disposed thereto a fixed clutch member 104adapted to be engaged by a movable clutch member 105 also on shaft 30upon the operation of the clutch actuating handle 106 also at the rearend of the machine platform 26. These clutch members 104, 105 whenconnected, will connect the operating gears and shafts of the brushelements with the driving. shaft.

As shown in Fig. 3, the steering handle 15 is moved above a segmentplate 107 at the rear end wall of the machine provided with teeth 108 atits upper face between which the handle 15 is temporarily engagedaccording to the direction of driving the machine.

In operation, the operator starts the motor after the hopper 44 has beenfilled with sand or clay, according to thenature of the work to beperformed by the machine, and con nects the driving shaft by means ofthe clutch withthe motor shaft, and by the operation of the clutchhandles 103, and 106, either simultaneously or alternately, couples thedriving shaft with the brush-or rake-operating means as required, whilethe stone rake will rake the stones etc., encountered upon the conveyerwhich will transport the same into the stone-collecting vessel fromwhere they may be removed, if required or necessary. The opening in thehopper bottom is regulated according to the quantity of sand or clay tobe distributed over the ground by means of the hand-wheel 59. Accordingto requirement, either a plate 74 provided with rake teeth 75, or aplate 7 6 provided with a brush 7 7 may be placed into the frame 7 8.

It will be clear that according to the nature of the work to beperformed, the succession of the single operations is to be charged asvfor instance first the rakes may be used to level the ground, or theoperation of the rakes may be dispensed with and the ground be worked bythe brushes and rollers only for instance after a rain both of therollers may be used for leveling purposes.
